Letters Patent No. 110,765, dated January 3, 1871.

IMPROVEMENT IN CARPENTERS SHQOTlNG-BOARDS.

The Schedule referred to in these Letters Patent and making part of thesame.

I, JOSEPH Jouns, of the city of Newark, in the county of Essex and Stateof New Jersey, have iuvented certain Improvements in the OarpentersShooting-Board secured to me by Letters. Patent, No. 52,719, issuedFebruary 20, 1866, of which improvements the following is aspecification.

The first improvement relates to the bed-piece upon which the piece ofwood lies to be planed;

The second relates to the stop and to its adjustment; and

The third to an addition to 'the stop.

Figure lis a plan of the bed-piece, showing the improvements in bot-hbed-piece and stop;

Figure 2 is an end view of the same;

Figure 3 is the additional attachment to the stop;

Figure 4 is a top view', and

Figure 5 is an end view of the same.

A is the bed-piece, which, from the end'g/ to the stop, is a separatepiece from the main frame 5 B is the main frame;

C is the base-board 5 and D, the stop.

In providing for the elevation of the bed-piece A, it is essential thatits upper edge, next to the face of the plane, should be the center ofmotion, remaining close to the face of the plane, while the lower edgerecedes therefrom, asthe bed-piece is turned up to a required angle. Tothis end two rods, X, each a segment of a circle, Whose center is at zon the upper edge-line of the bed-piece, are att-ached' to and form partof the bed-piece A, and more in guides in the main frame B.

Upon the edge of the baseeboard C is a hinged screw-bolt, V; and to theback edge of the bed-piece there is attached a slotted bar, W.

The hinged bolt V goes through the slot in the bar WV, and the bar isheld in position by the thumb-nut az, securing the bed-piece A at anyrequired angle of inclination.

The frame B has, from the end of the bed-piece A, at z, its upper facelevel with the bed-piece, when that bed-piece lies flat on the frame,upon which level face the stop D is secured.

t and u (the latter shown by dotted lines in fig. Il) show two slots inthe level face, placed at rig-ht angles to each other.

A pin, d', passes through the slot u and the footpiece q of the stop'D,and a bolt, with a thumb-screw or nut, s, alsol passes through thefoot-piece q and through a slot, t, in the frame, by'which the stop ismade easily adjustable to any required angle, and is heldsecurely inplace ont-he frame.

As an additional support to long stuff when having `a bevel plane'd onits end, the frame, fig. 3, is made conveniently attachable to anddetachable from the stop D.

In the outer bar of that frame is a semicircular slot, which is asegment of a circle, whose-center is :i on the main frame.

A projecting support, k, held by athumb-screw, is by those meansadjustable, as may be required, to any desired inclination. v

Thus, having described my improvements,

\Vhat I claim, an'd desire to-secure by Letters Pateut, is

The bed-plate B and adjustable table A, in combination with'the stop D,all the parts b eing constructed, arranged, and operating in the mannerand for the purpose as shown and described.

JOSEPH JONES.
